When real-time frequency analysis is required on a large amount of data, such as with spectrum analysis, the required computation time can be much too long. In this case, the output frequency data (DFT) falls b
From Eqs. (15) and (16), it is clear that they can be interpreted as linear transformations and they convert one set of data from one domain to another (time to frequency and vice versa). The computation of X(k) in (15) takes N2 complex multiplications and additions, which gets large...

We based the computation of the Moran coefficient on the geodesic distance between the language coordinates as provided by Glottolog50, following suggestions in the literature51. We computed this coefficient using the geostan package46. In all cases, the coefficient was close to 0, indicating very...
Addressing interfacial effects during specimen preparation in cryogenic electron microscopy remains challenging. Here we introduce ESI-cryoPrep, a specimen preparation method based on electrospray ionization in native mass spectrometry, designed to allev
As a result, even more of a burden is put on the interpolation filter which leads to a bigger ROM and more computation. Thus, a need exists for an apparatus, system, and method to perform sample rate conversion in an improved and economical fashion. SUMMARY OF THE INVENTION Accordingly,...

In one embodiment, each element or stage of multirate filter 200 may be implemented using a polyphase structure to reduce the computation rate. A polyphase structure typically comprises multiple shorter filters that operate at different points in time. This technique may be referred to as polyphase...
